USB Power and Charging Port Controllers
WT6671P
| 【 General Description 】 |
| The WT6671P is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 specification. It is designed for USB Type-C® power source applications such as power adapters, wall chargers, car chargers, power banks, and etc. |
| The WT6671P minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, NMOS load switch driver, an 8-bit MCU, VCONN power and capless LDO to allow small form factor and low BOM cost. The WT6671P supports 5V to 20V USB PD 3.0 specification. One-Time-Programmable ROM is provided for program code and user configuration data. |
| The WT6671P is certified by USB Implementers Forum (USB-IF) for USB PD 3.0 (TID: 4996). |
